1. A device comprising:
a communication circuit configured to transmit messages to and receive messages from at least one control device;
a sensing circuit; and
a control circuit configured to:
detect, via the sensing circuit, a state change event associated with an electrical load that indicates a loss of power at the electrical load;
in response to the detection of the state change event associated with the electrical load that indicates the loss of power at the electrical load, transmit, via the communication circuit, at least one first message to the at least one control device;
determine, based on receipt of at least one second message from the at least one control device or a failure to receive the at least one second message from the at least one control device, that the loss of power is a result of a system power removal event; and
in response to the determination that the loss of power is the result of the system power removal event, transmit, via the communication circuit, at least one third message to the at least one control device that is configured to cause the at least one control device to return to a prior power state before the system power removal event, wherein the at least one third message includes at least one of an indication that the power removal event was the system power removal event or control instructions that include the prior power state of the at least one control device prior to the occurrence of the system power removal event.
